Growth of animals is promoted by inclusion in their feed of compounds of the formula ##STR1## in which Z is a glycosyl radical bonded via the anomeric carbon atom, R.sub.1 is hydrogen or an optionally substituted hydrocarbon radical having up to 30 Carbon atoms optionally interrupted by O, N or S, and R.sub.2 is hydrogen or an alkyl or aralkyl radical having up to 30 Carbon atoms optionally interrupted by O or substituted by groups containing oxygen or by halogen, with the proviso that COR.sub.1 is not an acyl group having 1-5 Carbon atoms when R.sub.2 is an alkyl group having 10-20 Carbon atoms.
动物生长可以通过在其饲料中添加以下化合物的形式得到促进:其中Z是通过异头碳原子连接的糖基自由基,R1是氢或者是一个最多含有30个碳原子,可以选择性地被O、N或S原子隔断的,也可以选择性地被取代的烃基团,而R2是氢或者是一个最多含有30个碳原子的烷基或芳烷基团,可以选择性地被O原子隔断或被含氧基团或卤素取代,条件是当R2是一个含有10-20个碳原子的烷基团时,COR1不能是一个含有1-5个碳原子的酰基团。
